From residue to glass
Wastewater treatment does not make unwanted materials disappear. After water is cleaned, residues remain. Liquid Relic investigates what these overlooked materials can become.
Billie van Katwijk incorporates residues from wastewater treatment into glass, where they influence colour and texture. Through experiments with fusing, slumping and lampworking, the research develops into a growing material archive alongside objects and jewellery.
At Dutch Design Week, Liquid Relic brings these different stages together: from raw residues and glass samples to prototypes and wearable objects.
